In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a screwless vehicle lamp fixing structure that is easy to disassemble, including a lamp cover 1, multiple first brackets 2 and a second bracket 3. A connecting cylinder 4 is fixed to one side of each of the multiple first brackets 2. An inclined surface 5 is formed on the inner side of the connecting cylinder 4, and a positioning block 6 abuts against the inner side of the inclined surface 5. The larger end of the positioning block 6 is fixedly connected to the outer side of the lamp cover 1. An expansion groove 7 is also formed on the inner side of the connecting cylinder 4. A first piston block 8 is slidably connected to the inner side of the connecting cylinder 4. A slot 9 is formed on the side of the first piston block 8 near the positioning block 6. Multiple mounting holes 10 are formed on the inner side of the slot 9, and ball bearings 11 are slidably connected to the inner side of the mounting holes 10. A plug rod 12 is fixed to the smaller end of the positioning block 6, and a slot 13 is formed on the outer side of the plug rod 12. A piston cylinder 14 is fixed to one side of the second bracket 3, and a hydraulic system is fixedly connected between the piston cylinder 14 and the multiple connecting cylinders 4. The oil pipe and the inner side of the piston cylinder 14 are slidably connected to the second piston block 15. A spring 16 is fixed to one side of the second piston block 15. One end of the spring 16 is fixedly connected to the inner side of the piston cylinder 14. A connecting rod 17 is also fixed to one side of the second piston block 15. A cam handle 18 is rotatably connected to the outer side of the connecting rod 17. A pin 19 is inserted between the cam handle 18 and the connecting rod 17. The inner diameter of the expansion groove 7 is larger than the inner diameter of the connecting cylinder 4. The diameter of the mounting hole 10 near the slot 9 is smaller than the diameter of the ball 11. The diameter of the mounting hole 10 away from the slot 9 is larger than the diameter of the ball 11. One end of the insert rod 12 is inserted into the inner side of the slot 9. The outer side of the ball 11 is engaged with the inner side of the slot 13. The interior of the hydraulic oil pipe is connected to the interior of the piston cylinder 14 and the interior of the connecting cylinder 4 respectively. One end of the connecting rod 17 extends through the inner side of the piston cylinder 14 to the outside.

[0023] The first bracket 2 and the second bracket 3 are fixed to the frame. When the headlight needs to be removed, the pin 19 on the cam handle 18 is pulled out, and the cam handle 18 is rotated to release the connecting rod 17. Under the push of the spring 16, the second piston block 15 squeezes the hydraulic oil in the piston cylinder 14, so that the hydraulic oil enters the connecting cylinder 4 through the hydraulic oil pipe, thereby pushing the first piston block 8 in the connecting cylinder 4 to move. During this process, the ball 11 on the first piston block 8 moves from the inside of the connecting cylinder 4 to the expansion groove 7. Since the inner diameter of the expansion groove 7 is larger than the inner diameter of the connecting cylinder 4, the ball 11 has more room to move, thus losing its locking effect on the slot 13. This allows the insert rod 12 to move freely out of the slot 9 on the first piston block 8, thereby quickly completing the disassembly operation. Through the above process, all fixed connections can be released simultaneously, greatly speeding up the disassembly operation of the headlight. This solves the problem that when multiple screws are used to fix the headlight to the frame, the screw positions are relatively narrow, and the hand movement space is limited, which affects the movement when removing the screws and causes inconvenience in operation.

[0024] The specific usage and function of this embodiment: The first bracket 2 and the second bracket 3 of this utility model are fixed on the vehicle frame. When it is necessary to disassemble the headlight, the pin 19 on the cam handle 18 is pulled out, and the cam handle 18 is rotated to release the connecting rod 17. Under the push of the spring 16, the second piston block 15 squeezes the hydraulic oil in the piston cylinder 14, so that the hydraulic oil enters the connecting cylinder 4 through the hydraulic oil pipe, thereby pushing the first piston block 8 in the connecting cylinder 4 to move. During this process, the ball 11 on the first piston block 8 moves from the inside of the connecting cylinder 4 to the expansion groove 7. Since the inner diameter of the expansion groove 7 is larger than the inner diameter of the connecting cylinder 4, the movement space of the ball 11 is increased, thereby losing the locking effect on the slot 13, so that the insert rod 12 can be freely moved out of the slot 9 on the first piston block 8, thereby quickly completing the disassembly operation. Through the above process, all fixed connections can be released simultaneously, greatly speeding up the disassembly operation of the headlight.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
